Quantitative trait loci associated with drought tolerance at reproductive stage in rice.
Drought is a major constraint to rice (Oryza sativa) yield and its stability in rainfed and poorly irrigated environments. Identifying genomic regions influencing the response of yield and its components to water deficits will aid in our understanding of the genetics of drought tolerance and development of more drought tolerant cultivars. Quantitative trait loci (QTL) for grain yield and its co...
متن کاملQuantitative Trait Loci Associated with Drought Tolerance in Brachypodium distachyon
The temperate wild grass Brachypodium distachyon (Brachypodium) serves as model system for studying turf and forage grasses. Brachypodium collections show diverse responses to drought stress, but little is known about the genetic mechanisms of drought tolerance of this species. The objective of this study was to identify quantitative trait loci (QTLs) associated with drought tolerance traits in...
متن کاملQuantitative Trait Loci Associated with Drought Tolerance in Common Bean
Drought stress is the major limitation of common bean (Phaseolus vulgaris L.) grown in subsistence farming systems worldwide. The objective of this study was to use single nucleotide polymorphism (SNP) markers from the BARCBean6K_3 Beadchip to identify quantitative trait loci (QTL) associated with traits related to drought tolerance in common bean. An intergene pool recombinant inbred line (RIL...
متن کاملIdentification and Mapping of Quantitative Trait Loci Associated with Salinity Tolerance in Rice (Oryza Sativa) Using SSR Markers
Salinity stress is one of the most widespread soil problems next to drought, in rice growing areas. ReducingSodium (Na+), while maintaining Potassium (K+) uptake in rice are traits that would aid in salinity tolerance.Therefore, the identification of quantitative trait loci (QTLs) associated with those for Na+ and K+uptake, will enable breeders to use marker-assisted selection...
متن کاملIdentification of Quantitative Trait Loci Controlling Cold Tolerance at the Reproductive Stage in Yunnan Landrace of Rice, Kunmingxiaobaigu
This study focused on a Yunnan landrace of rice, Kunmingxiaobaigu, to identify quantitative trait loci (QTLs) controlling cold tolerance at the reproductive stage using DNA markers. A linkage map with 16 linkage groups covering 1,354.4 cM with a total of 122 markers was constructed based on an F2 population consisting of 250 individuals of a cross between Kunmingxiaobaigu and a Japanese variety...
